If you want to use the scatter-gather mode, you must add

Have you tested the scatter-gather mode on the chip ? Does that work at
all ?
Note: You could try this by setting a buffer_size > 1M for the ETR and use
it as a sink from the sysfs mode.
Yes the chip supports scatter-gather mode[1]. But is it required in
dt node since it's an optional property?
